To all whom it ina/y concern:

Be it known that l, Nit'iionls P. Mn'rnoiflnoluf, asubject oi' thellzar of Russia, residing at lridgeport, county ol' `Fairfield, State of Connecticut. have invented a new and. useful lllechanical Fountain, ot which the following is a specification.

This invention has for its object to provide a mechanical fountain comprising two reservoirs placed opposite to each other and carried by a rotating hub; a tank and connections whereby l am enabled` to produce a jeter vfountain by placing the 'l'ull reservoir uppermost, and starting the tlow again, with but an instants stoppage, by reversing the reservoirsas soon as the upper reservoir is exhausted.

ln order to produce a simple and inexpensive device oi this charz'icter'suitable for use in connection with aquariums and Wherever a jet lol' water may be required, .l have devised the novel mechanical lountain oi which the `following description in connection with. the accompanying drawiiig is a specification, reference cln'iracters being used to indicate the several mrts: i Figure 1 is a vertical sectional view illustrating the construction and operation oll my novel fountain; Fig. 2 an end View ol the hub` and reservoir detached; Fig. 3 a section ol the hub and reservoirs on the lino SW3 in Fig. and. Fig'. 4 is a longitudinal sect ion et the. body detached.

l() denotes the body which is round and is )reterably made taperin. as shown. The

ody is rigidly secured to standards 11 which may be ot any required shape or design and which also support a tank 12 at a distance above the body. 'l`hc body is provided with three ducts or passages indicated by 13, 14 and 15.

16 denotes the hub an'l 17 reservoirs laced on o posite sides ot' the hub and rigidly secureilithereto. The hub is provided with a central opening 1S which receives the body with a ground :lit so as to prevent leakage,' the body and opening 18 being preterably correspondingly tapered, as shown7 although this construction is not essential. l have shown the hub as retained in position on the body by a tightly iitting collar 1).

2() denotes a pipe leading from the tank downward to the body, and 2l a pipo leading from the body upward to the tank and provided willi a nozzle 2 which extends llp\\'.a1d in the. tank slightly above the normal water level. `Fach reservoir provided with an induction pipe 23 and an eduction pipe 24. Tholower reservoir in Fig. 1 is inthe receiving iosition and the upper reservoir is in the disc iarging position. rl`he induction and mhletion pipes are 'irmly seated in the hub and `extend through to the central opening and are adapted to register with the ducts in the body. 'lhe induction iipes extend from the central opening in the liub nearly to the bottoms of the reservoirs (when in the re eeiving position) and the eduction pipes eX- tend from near the tops` ot the reservoirs to the central opening in the hub. The mouths ot' the eduction pipes are, provided. with guards 25 which retain float valves 26 in place so that they will rise and t'all with the water in the reservoirs, and when the water has all passed out ol a reservoir will close the eduction pipe. and prevent the .passage of air therefrom. Pi ie 2() communicates with duet 13 in the body and pipe 21 co1nnninicales with duct 15 in the body.l Duct,- 14. extends through the body at such an angle as to register with the induction pipe of a discharging reservoir and the ednction pipe gol a. receiving reservoir7 said duct serving as an air passage only.

y rl`he operatitm will be readily understood l'roni Fig. 1.. ln the position shown, water is passing l'roni the. upper reservoir throughan eduction pipo Q4, duet 15 in the body and pipe 2" to nozzle 22 l'roin which it passes in the form ot' a spray. As fast water is delivercd in the tank, it passes therefrom by means ol pipe 20, duct 123 in the body and. an induction pipe 22% to the lower reservoir. is the upper reservoir is exhausted by the passage of water tothe tankY the lower I servoir is correspondingly tilled by water received from the. tan li. The lower reservoir becomes tilled practically simultaneously with the emptying ol the upper reservoir. As the water rises in the lower reservoir, air will ne forced therefrom into the upper reservoir through duct 1l, and the air in the upper res ervoir will torce water therefrom through the upper eduction pipe, duct 1.3, pipe 2l and the nozzle.. During,r the tlling'ol the lower reservoir, the lloat valve the-rein 4will rise in the guard un til it engages the.. mouth otx the eduction pipe'. 'lhe seating ol the lower lloat valve will prevent the passage ot Water t'roni the lower reservoir to the upper reservoir, and the engagement of the u per float valve with the mouth of the upper @duction pipe f hour when the water in the upper reservoir is eX- hausted will prevent the passage of any air from the upper reservoir through duct and pipe 21, thus retaining the air pressure in the reservoirs. The operation of my novel fountain may be compared to the o eration of an lass. When the water iias all passed from" the u' per reservoir a corresponding amount will ave passed into the lower reservoir and the fountain will be started into operation .again by reversing the reservoirs, that is by givingthe hub a half turn and placing the iilled lower reservoir in the place previously occupied by the exhausted upper reservoir, care eing taken of course to make the inner ends of the induction and eduction ipes in the hub register with ducts 13 and 15' in the body. Owin to the closeness of the it of the hub on the ody, the reservoirs will be self-retaining inoperative position but suitable vsetting and retaining devices may be provided if preferred. These have not been shown, however, asspeciically they form no portion of the present invention.

Having thusdescribed my invention l claim.:

1. A mechanical fountain com rising two oppositely placed reservoirs, a hu by which said reservoirs are carried, a body on which said hub is mounted to rotate and which is provided with ducts, a tank above the reservoir, induction and eduction pipes in the res; ervoirs which are adapted'to register 'with ducts'in the body, pipes leading from the tank to the body and from thebody to the tank, and means for preventing the passage of waterl from the lower reservoir to the upper reservoir.

2. in a device of the character described, the combination with a tank, two oppositely placed reservoirs each provided with .an in- .uction and an eduction pipe and a hub by which the yreservoirs are carried, of a body having ducts adapted to register with the induction and eduction pipes, and pipes communicating with ducts in the body and leading yout of and into the tank, means being provided whereby Water can not Ipass into the upper reservoir'nor air escape t erefrom.

if. n a device of the character described, the combination with a body having ducts, a

tank and a hub mounted to rotate on the body, of oppositely placed reservoirs carried by the hub, induction and eduction pi es in the reservoirs adapted to register Wit the ducts, a guard extending from the mouth'of each eduction pipe, oat, valves in said guards, and pipes `communicating with ducts in the body and leading into and out of the tank, the float valve 1n the lower reservoir preventing the passage of water therefrom to the upper reservoir, and the float valve in the upper reservoir preventing the escape of air therefrom.

In testimony whereof I ahX my signature,

in presence of two witnesses.
